The Paris La Défense Tour Ariane Centre is located in the 152m high Tour Ariane, in a prominent open position within the La Défense business district, with sweeping views across the city. The aluminium-clad 36-storey tower was built in 1975 in the first phase of development of La Défense, now a focus for top businesses, research facilities and major events. The entrance has since been modified and the building is being refurbished. Other long-term tenants in this tower include leading national and international companies from the banking, insurance, telecoms, data management, consultancy and manufacturing sectors. There is an on-site restaurant and the centre is close to RER train and other public transport links.
